Complex Analysis
Save
Complex analysis is a branch of mathematics that deals with functions of complex variables. It is a vast and multifaceted subject with applications in many different fields, including engineering, physics, and computer science.
What is a complex number?
A complex number is a number that has two parts: a real part and an imaginary part. The real part is the part that you would normally think of as a number, such as 3 or -5. The imaginary part is the part that is multiplied by i, where i is the imaginary unit. The imaginary unit is a number that is equal to the square root of -1: i2 = -1.
Complex numbers can be written in the form a + bi, where a is the real part and b is the imaginary part. For example, the complex number 3 + 4i has a real part of 3 and an imaginary part of 4.
